To examine the literature assessing safety of air travel relating to coronavirus disease 2019 (COVID-19) transmission from January 2020 to May 2021. The COVID-19 pandemic has had an unprecedented impact on air travel and global mobility, and various efforts are being implemented to determine a safe way forward. As the pandemic evolves, so do the challenges that force various stakeholders, including the aviation industry, health authorities, and governments, to reassess and adapt their practices to ensure the safety of travellers.
The literature was reviewed for multiple aspects of air travel safety during the COVID-19 pandemic. Recurring themes that surfaced included the pivotal role of commercial air travel in the geographic spread of COVID-19, the efficacy of travel restrictions and quarantines, inflight transmission risk and the role of preventive measures, the utility of pre and post flight testing, the development of effective vaccines and subsequent challenges of vaccine passports, and the ongoing threat of novel highly transmissible variants.
Much uncertainty lies ahead within the domains of these findings, and ongoing research, discourse and review will be necessary to navigate and determine the future direction and safety of air travel. Recovery will be slow, necessitating innovative, multipronged and collaborative solutions.
检查 2020 年 1 月至 2021 年 5 月与 2019 年冠状病毒病（COVID-19）传播相关的航空旅行安全文献。COVID-19 大流行对航空旅行和全球流动产生了前所未有的影响，正在实施各种努力以确定安全的前进道路。随着大流行的发展，迫使包括航空业、卫生当局和政府在内的各种利益相关者重新评估和调整其做法以确保旅行者安全的挑战也在不断变化。
对 COVID-19 大流行期间航空旅行安全的多个方面进行了文献回顾。出现的反复出现的主题包括商业航空旅行在 COVID-19 的地理传播中的关键作用、旅行限制和检疫的效果、飞行中传播风险和预防措施的作用、飞行前后检测的效用、有效疫苗的开发以及随后疫苗护照的挑战，以及新型高传染性变体的持续威胁。
这些发现和正在进行的研究、讨论和审查领域存在很大的不确定性，需要进行导航并确定航空旅行的未来方向和安全性。复苏将是缓慢的，需要创新、多管齐下和协作的解决方案。
